[Ten years of development of chemical equipment] 1202-2023 Vacuum jacketed cryogenic valve for liquid hydrogen passed the liquid hydrogen internal cooling method type test

Thread Content

Looking at the ten years of development of chemical technology, we praise the prosperity and strength of China in the prosperous age. It is more lively and more exciting with everyone's participation. [Ten Years of Development of Chemical Equipment] Continue to update summary posts, welcome to participate in the discussion https://bbs.hcbbs.com/thread-3576046-1-1.html Prevention first, life first -------------------------------------------------- Recently, the vacuum jacketed cryogenic valve for liquid hydrogen developed by Suzhou Neway Valve Co., Ltd. ("Neway Valve") located in Fengqiao Street, Suzhou High-tech Zone, Jiangsu Province, obtained the patent. * * Special equipment type test certificate issued by the Special Pump and Valve Engineering Technology Research Center. This marks that Neway Valve has become the first valve manufacturer in China to use the liquid hydrogen medium internal cooling method for type testing, and all performance indicators meet the standard requirements. In accordance with the T/CGMA 0405-2022 "General Test Method for Cryogenic Valve for Hydrogen" standard, this series of products were used in my country's Aerospace Product Testing Center with a liquid hydrogen internal cooling method that is as stringent as the actual working conditions. After 100 pressurized cycle life tests under liquid hydrogen working conditions, all performance indicators are in line with the standard requirements of T/CGMA 0407-2022 "General Technical Specification for Cryogenic Valve for Hydrogen".
